| Abstract: | This paper applies bidimensional empirical mode decomposition(EMD) technique to multi-scale non-linear analysis and decomposition of geophysical and geochemical data of Gejiu area and geophysical and geochemical anomalies are separated and delineated so as to provide deep level ore information.Each component of EMD decomposition has its practical geological significance.EMD will be a new technique for geophysical and geochemical data procession. |
